1 i <br />' Quarterly groundwater sampling has been conducted since 1996 This report is the fourth quarter 2001 <br /> groundwater monitoring report which represents the second report in the Phase IX groundwater sampling <br />' effort and presents the results of continued groundwater sampling following the schedule presented in Table <br /> 1-1 <br />' Table 1-1 <br />' Sampling Schedule <br />' Quarter Monitor Wells to be Sampled <br /> First MW-2, MW-2A and MW-9 <br />' Second MW-2, MW-2A, MW-3A, MW-4, MW-6, MW-7 and MW-9 <br /> Third MW-2, MW-2A and MW-9 <br />' Fourth MW-2, MW-2A, MW-3A, MW-4, MW-5, MW-6, MW-7, and MW-9 <br /> 2.0 FIELD SAMPLING SUMMARY <br />' Groundwater samples were collected from monitor wells MW-2,MW-2A MW-3A MW-4 MW-5 MW- <br /> MW-7, and MW-9 (Figure 1-1) on February 5, and 6 2002 In addition an equipment blank water sample <br /> and a duplicate sample from MW-2A was collected Groundwater sampling data sheets forthe monitor wells <br /> are presented in Appendix B <br /> Water levels 1n all wells were measured on February 5, 2002 The standing water volumes within wells <br /> scheduled for sampling were calculated using water levels measured in each well at the time of sampling and <br /> total well depths A submersible pump was used to purge three well casing volumes from each of the <br /> monitor wells <br /> At the beginning and during the purge process, the temperature, pH, and specific conductance of theur e <br /> P g <br /> water were measured This information was recorded on a sampling data sheet Groundwater samples for <br /> benzene,toluene,ethylbenzene,and xylene(BTEX)and for total petroleum hydrocarbons as gasoline(TPH- <br /> G) analysis were collected from the wells with a disposable bailer and nylon string The groundwater <br /> samples were transferred into 40 ml glass sample containers Sample containers were checked for air <br /> bubbles The sample containers were sealed in a plastic bag,placed with ice in an insulated chest,and logged <br /> on a chain-of-custody form for delivery to the analytical laboratory <br /> f <br /> The pump used to purge and sample the wells was thoroughly cleaned prior to each use by placing it into a <br /> container of tap water and washing the outside of the pump The disposable hose was discarded after purging <br /> each well <br /> • <br /> LIPROXCTSISANJOQIHSA11QO1R1-T WPD 2 <br />
